Join Peggy Fisher for an in-depth discussion in this video Flowcharting and UML diagrams, part of Up and Running with Java.
- Flowcharts are a great way to create…a visual representation of our program flow.…UML Diagrams, Unified Modeling Language,…also provide a visual of any classes we need to create.…When creating flowcharts, it forces us to break our programs…down into pieces, otherwise known as stepwise refinement.…This shows us the processes needed to create…our final solution.…From these flowcharts, we can start to encapsulate…portions of our code into smaller methods.…Here are some of the basic symbols that we will be…using during this course.…
A start and end symbol, which is a round circle,…a process, or a rectangle,…a decision, which is a diamond,…for data we'll use a parallelogram,…and we also have a symbol for files…that looks like reports.…Let's take a simple problem and use a flowchart…to describe our solution.…How about we model a cash register at a grocery store?…What is the flow of this process?…As you can see at the top, we have our start circle.…The first thing we do is an action item, or a process…that says scan the item to add to total costs.…
